Both elid-wel1s l? are prefiero-bly detml'mlile from moin seetioo A., so that l', partiooler section A may have Iother simim eeotione gmiged or :ittaohed. thereto ot both its opposite sides, one 'pair of emflovellll.: .B being only required. for the box ".vlietlier used a unit with o single malin. or body-:seetion A or eolnfrged by se Y'.- erol mei'nfseetiois ganged or associated edgewise togetlior, s lo, respoetively, in Figo. l., 5, and 7.

Moin section A., wlilioli ie approximately `lli-e pe .in eide elev tion., )referably stamped op or @them formed. rom e sinblonk to integrally include is adapted to be suitably secured. At its diagonal Wall-portions 3 3 therebetween,l

the walls of section A being of suitable stiffness and wall-portions 3 being provided with suitable knock-outs 4 for the passage of electric wires and the like into and from the box, as will be well understood. At its front edge, each side-wall 1 is provided preferably centrally with an outwardly-projecting perforated ear 5, to which ears 5 the switch or the like arranged and contained within the box outer corners, each side-wall 1 of box-section A"`is also slightly bent or displaced inwardly to provide obliquely disposed lips 6, for purposes hereinafter appearing. Each sidewall l o'f section A is further provided with y a pair of short slots 7 7, said slots lying vadjacent to, and extending parallel with, the opposite side edges of the wall, as clearly seen in Figs. 8, 9, and 10.

Each wall -B, which is also preferably stamped up from a sheet of suitable substantially stiffl or rigid metallic material into the form seen in Fig. et to fit upon section A at its end, Wall B being of such shape and size relatively to section A as to neatly overlie the side edges of said rear wall 2 and both said side walls 1. At its opposite sides, wall B is preferably integrally provided with outwardly presented oppositely disposed approximately rigid tongues 8 8 offset inwardly from the Wall. These tongues 8 8', while suitably offset inwardly from the same face of wall B, extend approximately longitudinally with wall B and are adapted to endwise fit in slots 7 7, one of said tongues, as, for instance, tongue 8, being preferably rounded at its corners, as seen in F ig. l, and slightly reduced in length relatively to opposite tongue 8. At its opposite outer corners, each wall B is also provided with small inwardly-projecting lugs 9 5) adapted to fit -upon and engage with said lips 6 6 when operating slot 7, opposite tongue 8 at the c same time engaging fully with its slot 7, wllcreu )on section A and wall B are firmly and tig itly detachably assembled and locked together without the employment or use of screws or similar fastening members. In such edgewise rearward movement ofrwall B relatively to and upon section A, the metal of section A at its side Walls A is, under the forced engagement therewith of tongue 8 of wall B, somewhat sprung outwardly to permit the entrance into, and locking enggement with, slots 7 of the tongues 8 8. u all B fitting upon section A as described, with its tongues 8 8 in locking engagement with said slots 7, the lugs 9 removably fit upon and engage with said lips 6 and thereby prevent spreading of section A at the front edges of its side walls A.l To disengage wall B from section A, a sharp blow or two or other suitable pressure applied to and upon the diagonal edge of wall B serves to at once force tongue 8 from lockso ing engagement with its slot 7, the metal of section A being again somewhat sprung outwardly under the forced engagement therewith of tongue 8', when tongue 8 may be also removed from locking engagement with its 35 slot 7 and the wall B then fully detached from section A.

Threaded into each side wall 1 of section A at suitable points thereupon, is an alining pair of properly spaced apart studs, headed screws, or the like 10, whereby a fastening member or bracket C, seen in )erspective in Fig. 6, is adapted to be adjustalily secured to each of the side-walls 1 of the box in various operative positions to meet the particular conditions or requirements of different installations. This bracket C comprises a main plate or body-portion 11 and a flange 12 projecting approximately at right angles from portion 11. Centrally main or plate portion 11 of bracket C is provided longitudinally with an elongated open-end slot or aperture 13. Portion 11 of bracket C is also provided with a pair of slots or apertures 1.4 14 disposed on opposite sides of, and extending parallel with, center slot 13, each slot 14. being preferably widened midway its length, as at 14', to permit the entrance therethrough of the heacl of one of said screws 10. It will be noted that screws 10 are threaded into wall 1 of section A at such distance apart to correspond with the distance between the slots 1& 11 of bracket C, the flange 12 of bracket C being also provided longitudinally relatively to the bracket with a pair of screw preferably open-end slots or apertures 14) 15 spaced apart likewise a distance equal to the distance between slots 1-l 14. Each of the slots of bracket C has a width sufficient only to accommodate the shank of a` screw 10, whereby, on tightening said screw, bracket C, being in one of its several positions relatively to the box and said screws 10 engaging with either slots 15,\ slots 14, or center slot 13, may be securely-" held in adjusted positionupon the box.

In installing boxes of this class, it is desirable that the box, at its open front'side, should be approximately flush with the surface of the wall, in order that the face or 6. the edges olE they bmi;
